I'm working with Mathematica 8 on Linux. First, from the command line: >>mkfifo aPipe In Mathematica, OpenWrite["aPipe"] works like a charm. I can write to it and get the result on the command line using cat. But, OpenRead["aPipe"] fails with "OpenRead::noopen: Cannot open aPipe." Why isn't Mathematica able to open the pipe for reading? Can anyone suggest a workaround for reading lines out of a fifo? Thanks -Ian
